Virus - 1/2 Poison
Infect - 1/2 + Absorb Poison (you get this way too late in the game)
Zombie - undead and/or resist Zombie
Stone - resist Stone
Death - resist Death
Holy - null or absorb Holy (there is a Holy Ring after all)
Holy+ - absorb Holy and/or 1/2 MP reduction option
Nuke - ignore Mblock
Nuke+ - 4x hit
Reduce - resist Death and/or 1/2 Earth
Gravity - resist Death and/or Absorb Earth
Quake - null Earth
X-Zone - resist Death
Meteor - ignore Mblock
Tornado - null Wind and/or resist Weak + once weak, always weak
Flare - 1/2 Fire and/or 1/2 Wind and/or ignore MBlock
Scan - 1/2 all elementals (the idea is to remove all weaknesses on yourself)
Mute - resist Mute
Sleep - resist Sleep
Conf - resist Conf
Stop - add Haste+Slow status (so it prevents other time statuses, as inflicting initial Stop status is the stupidest possible idea ever, especially if it's permanent)
Imp - resist Imp
Wall - add Wall status
Dispel - add resistances that can be normally be dispelled (Vanish, Image?, Berserk)
Slow2 - prevent back attack
Haste2 - raise preemptive strike
Vanish - (shouldn't it do more than add Shell?) add Image status
Attack - add magic damage boost
Cure+Life spells - add Weak status
Heal - resist Poison and/or 1/2 Poison damage
Remedy - too bad we already have the neutralizer... maybe resist a smaller subset of status, primarily those that prevent command of a character (Sleep, Stone, Berserk, Muddle) or those that don't prevent commanding a character (Poison, Seizure, Blind, Mute)
Rasp - (if it didn't have the HP/MP boosts.. or in addition to those boosts) adding one of the MP reduction options
I was thinking more towards level 1 elementals = 1/2, level 2 = null, level 3 = absorb.. but whatever works I guess.
I can do that, I'm just afraid it might be a bit too powerful, I forget how many of the level 3 learn relics you can get.
You start picking them up late WOB via steals, and you have full access to them @ Thalmasa in the WOR once you get the Airship.
I don't see the logic behind MP Absorber having Psych as its spell attached... maybe Rasp would make more sense there...
